Frozen's presence in Once Upon a Time is heating up! The latest character from the animated Disney film to make the move to the ABC series is Pabbie, the gentle rock troll king. And Once has pegged a man with rock-solid pipes to provide the voice.

John Rhys-Davies, known for his roles as Sallah in the Indiana Jones films and Gimli the dwarf in the Lord of the Rings trilogy, will lend his vocal chords to a computer-animated version of Pabbie. The news was announced Monday by showrunner Adam Horowitz on Twitter, who wrote, "We're thrilled to welcome John Rhys-Davies to the #OnceUponATime family as the voice of everyone's favorite rock troll -- Pabbie!"
